Description
NFC-TS4311 Touchscreen Fan Coil Controller with Non-volatile Programmable Filter Service Timer
The NFC-TS4311 is a 4.3 inch Colour TFT Touchscreen, Proportional + Integral Fan Coil Controller. The Unit has 2 NTC Sensor Inputs, 1 Universal input for remote changeover or changeover NTC Sensor, 2 Digital Inputs (Key Card/Occupancy and Window Input), 5 Optically Isolated SSR (Solid State Relay) Outputs (1 x Raise Lower or 2 x PWM-ON/OFF and 3 Digital Fan Speed) and 3 Analogue 0-10 Volts DC Outputs (1 Heating, 1 Cooling and 1 Analogue Fan Speed). The Controller supports two Pipe and four Pipe System.
The Raise Lower Outputs are TPC (Time Proportional Control with adjustable valve opening time). The Fan Coil Controller has built-in real time clock with backup Super-capacitor therefore eliminates the use of battery. The NFC-TS4311 Fan Coil Controller works on 24VAC/DC and is Wall Mount with only 25MM Thickness.
